# What Is The Electrical Schematic Diagram Symbol For A Diode

A diode is a two-terminal electronic component that allows current to flow in only one direction. It is a semiconductor device, which means that it has properties of both a conductor and an insulator. Diodes are used in a wide variety of electronic circuits, including rectifiers, amplifiers, and oscillators.

The electrical schematic diagram symbol for a diode is a triangle with an arrow pointing in the direction of current flow. The anode (positive terminal) of the diode is represented by the point of the triangle, and the cathode (negative terminal) is represented by the tail of the arrow.

The following diagram shows the schematic diagram symbol for a diode:

Diodes are available in a variety of shapes and sizes, but they all have the same basic function. They are used to control the flow of current in electronic circuits.

In addition to the schematic diagram symbol, diodes are also often represented by the letter "D". For example, a diode in a circuit diagram might be labeled "D1" or "D2".
